Circumference = pi*diameter or 2*pi*radius
EDIT: To find the diameter, using the circumference - you divide the circumference by the value of Pi - Snakester1962 (Supervisor)
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
diameter X pi = circumference What you call edge is usually called circumference. pi = 3.1416
it uses to find out thearea and circumference of circle. diameter=2*radius
C = pi*d Remember the circle eq'n To find 'd' we algebraically rearrange. to d = C/pi

It is the ratio of the circumference (C) and the diameter (D) of a circle. Using pi and the diameter of a circle, you can work out the circumference.

16.55cm - If you want to work it out, you will need to divide the circumference by pi.
C = pi*d Remember the circle eq'n To find 'd' we algebraically rearrange. to d = C/pi
circumference = pi*100mm
The answer will depend on what information you have: radius, area, diameter.
Divide the cirumference by 3.14
The value of pi = circumference/diameter
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
